DESCRIPTION OF EMBODIMENTS

The therapeutic agent for the ophthalmic disease of the present invention comprises, as an active ingredient, a vascular endothelial growth factor (VEGF) receptor inhibitor or an epidermal growth factor (EGF) receptor inhibitor having a property to be retained in a posterior eye tissue when systemically administered.

The vascular endothelial growth factor (VEGF) receptor inhibitor is not particularly limited, and a substance known in the art can be used which has inhibitory activity against vascular endothelial growth factor (VEGF) receptor and has a property to be retained in a posterior eye tissue when systemically administered.

The epidermal growth factor (EGF) receptor inhibitor is not particularly limited, and a substance known in the art can be used which has inhibitory activity against epidermal growth factor (EGF) receptor and has a property to be retained in a posterior eye tissue when systemically administered.

The therapeutic agent for the ophthalmic disease may comprise one vascular endothelial growth factor (VEGF) receptor inhibitor or may comprise two or more vascular endothelial growth factor (VEGF) receptor inhibitors.

The therapeutic agent for the ophthalmic disease may comprise one epidermal growth factor (EGF) receptor inhibitor or may comprise two or more epidermal growth factor (EGF) receptor inhibitors.

The therapeutic agent for the ophthalmic disease may comprise one or more vascular endothelial growth factor (VEGF) receptor inhibitors and one or more epidermal growth factor (EGF) receptor inhibitors.

The “posterior eye tissue” in the “property to be retained in a posterior eye tissue when systemically administered” for the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor used in the therapeutic agent for the ophthalmic disease of the present invention refers to the choroid, the retina, the sclera, or the optic nerve and preferably refers to the choroid and/or the sclera or the retina, more preferably the choroid and/or the sclera. The “property to be retained” in the “property to be retained in a posterior eye tissue when systemically administered” for the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor used in the therapeutic agent for the ophthalmic disease of the present invention specifically means that the compound has a half-life of 30 hours or longer in the choroid and/or the sclera when administered (preferably by intravenous injection) to a Brown Norway rat. The half-life in the choroid and/or the sclera is preferably 35 hours or longer, more preferably 40 hours or longer. In this context, the compound that remains in the posterior eye tissue (choroid and/or sclera, retina, etc.) localizes longer near the target (VEGF receptor or EGF receptor) in the tissue, as compared with a compound that does not remain therein. Thus, an effect based on the mechanism of action of the compound (inhibitory effect on the phosphorylation of VEGF receptor or EGF receptor) is maintained for a longer time. Finally, its pharmacological effects (angiogenesis inhibitory effect, suppressive effect on increase in vascular permeability, and other pharmacological effects based on the inhibitory effect on the phosphorylation of VEGF receptor or EGF receptor) are more strongly exerted. Furthermore, the compound that remains in the posterior eye tissue accumulates in the tissue by continuous (repetitive) administration and increases its exposure in the tissue, as compared with a compound that does not remain therein. As a result of these effects, the pharmacological effects of the compound are more strongly exerted in the posterior eye tissue.

Examples of the systemic administration method include, but are not particularly limited to, oral administration, intravenous injection, intramuscular injection or subcutaneous injection, sublingual administration, transnasal administration, ocular instillation, inhalation, and transdermal administration. Oral administration, intravenous injection, intramuscular injection or subcutaneous injection, or ocular instillation is preferred, and oral administration or intravenous injection is more preferred. The recipient of the systemic administration is not particularly limited as long as the recipient is a mammal. A human, a monkey (e.g., a cynomolgus monkey), a rabbit (e.g., Kbl:Dutch), a mouse (e.g., 129SVE), or a rat (e.g., Brown Norway) is preferred, and a human, a monkey, or a rat is more preferred.

Whether or not the compound has the property to be retained in a posterior eye tissue when systemically administered can be determined by, for example, the following approach: the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor is dissolved in an organic solvent such as dimethylacetamide (DMA) and then diluted with saline containing polyoxyethylene sorbitan monooleate (polysorbate 80 or Tween 80) or the like to prepare an intravenous dosing solution. This intravenous dosing solution is administered to a Brown Norway rat. After a given interval from the administration, for example, 24, 72 and 168 hours after the administration, blood is collected. Then, the rat is euthanized while the eyeballs are excised. A posterior eye tissue such as the choroid and/or the sclera, the retina, or the optic nerve is harvested therefrom. A given amount of an aqueous solution containing an organic solvent (e.g., a 50 vol % methanol solution) is added to the harvested posterior eye tissue, which is then homogenized, for example, to prepare an assay sample. The drug concentration in this assay sample can be measured using a liquid chromatograph-tandem mass spectrometer (LC/MS/MS) to measure the compound concentration in the posterior eye tissue in the case of systemic administration. The elimination half-life of the compound in the posterior eye tissue can be further calculated from time-dependent change in compound concentration in the posterior eye tissue.

The vascular endothelial growth factor (VEGF)-related disease is preferably wet age-related macular degeneration, myopic choroidal neovascularization, branch retinal vein occlusion, central retinal vein occlusion, macular edema following central retinal vein occlusion, diabetic macular edema, proliferative diabetic retinopathy or neovascular glaucoma.

Examples of the epidermal growth factor (EGF)-related disease include wet-type (neovascular or exudative) age-related macular degeneration (wet-AMD), dry age-related macular degeneration, choroidal neovascularization, myopic choroidal neovascularization, macular edema, macular edema following central retinal vein occlusion, diabetic macular edema, proliferative diabetic retinopathy, glaucoma, neovascular glaucoma, ocular inflammation, retinoblast, branch retinal vein occlusion, central retinal vein occlusion, retinopathy of prematurity, angioid streaks of the retina, retinal artery obstruction, corneal neovascularization, pterygium, uveal melanoma, uveitis, epiretinal membrane, corneal subepithelial fibrosis, dry eye, and meibomian gland dysfunction.

The epidermal growth factor (EGF)-related disease is preferably wet age-related macular degeneration, myopic choroidal neovascularization, branch retinal vein occlusion, central retinal vein occlusion, macular edema following central retinal vein occlusion, diabetic macular edema, proliferative diabetic retinopathy or neovascular glaucoma.

The pharmaceutical composition of the present invention can be used in the treatment, prevention, etc. of the vascular endothelial growth factor (VEGF)-related disease or the epidermal growth factor (EGF)-related disease and, among others, is preferably used in the prevention, treatment, etc. of ophthalmic diseases such as wet-type (neovascular or exudative) age-related macular degeneration (wet-AMD), macular edema following central retinal vein occlusion, myopic choroidal neovascularization and diabetic macular edema whose indications have been obtained for existing anti-VEGF inhibitors (intravitreal injections), and proliferative diabetic retinopathy, neovascular glaucoma, uveitis and retinopathy of prematurity on which the therapeutic effects of anti-VEGF inhibitors (intravitreal injections) have been clinically reported, albeit by off label indication.

In the epidermal growth factor (EGF)-related disease, a pathological condition is probably caused by angiogenesis or increase in vascular permeability in the eye. The pharmaceutical composition of the present invention can be used in the treatment, prevention, etc. of the epidermal growth factor (EGF)-related disease and, among others, is preferably used in the prevention, treatment, etc. of ophthalmic diseases such as wet-type (neovascular or exudative) age-related macular degeneration (wet-AMD), macular edema following central retinal vein occlusion, myopic choroidal neovascularization and diabetic macular edema on which efficacy ascribable to an angiogenesis inhibitory effect or a suppressive effect on increase in vascular permeability in the eye has been confirmed.

As for the ophthalmic diseases as described above, for example, favorable therapeutic effects (recovery of best-corrected visual acuity, histological amelioration such as thinning of the retina thickened due to a pathological condition, etc.) have been clinically confirmed by the intravitreal injection of anti-VEGF inhibitors, and the inhibition of angiogenesis or the suppression of increase in vascular permeability in the retina or in the choroid has been non-clinically confirmed by the administration of EGF inhibitors. Hence, the clinical efficacy of these drugs is expected. However, for example, the existing anti-VEGF inhibitors (intravitreal injections) have high therapeutic effects, but put an enormous load on patients themselves, their families and health-care professionals, which is a social concern, because their administration route is intravitreal injection and continued treatment is necessary due to high rates of recurrence or the like. In light of these circumstances, there is a demand for the development of drugs (oral agents, eye drops, etc.), for the ophthalmic diseases as described above, administrable through a noninvasive and convenient route other than intravitreal injection, from the viewpoint of reduction in load on patients themselves, their families and health-care professionals, etc. In this respect, the therapeutic agent for the ophthalmic disease of the present invention is useful because the active ingredient can be administered to a patient through a route such as ocular instillation.

The dosage form of the therapeutic agent for the ophthalmic disease of the present invention is not particularly limited and is preferably a liquid formulation (a solution). The solution is more preferably a suspension formulation or a solution formulation.

A portion or the whole of the components of the therapeutic agent for the ophthalmic disease of the present invention, or a freeze-dried powder thereof may be dissolved or dispersed in water or the like to prepare the therapeutic agent for the ophthalmic disease of the present invention.

The method for producing the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor in a nanoparticle form in the therapeutic agent for the ophthalmic disease of the present invention is not particularly limited. The vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor in a nanoparticle form can be produced by a nanoparticulation method, such as milling, which is generally used in the pharmaceutical technical field.

The nanoparticulation method can involve, for example, milling the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor using a commercially available instrument (zirconia container, zirconia balls, etc.), a commercially available nano pulverizer, or the like, followed by purification, etc. using a commercially available centrifuge or the like to produce the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor in a nanoparticle form. Alternatively, a solution of the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor can be crystallized by stimulation in a liquid phase or a vapor phase to produce the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor in a nanoparticle form.

In the milling step, the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor as well as one or more components selected from a thickening agent, a surfactant, a dispersion media, a preservatives and an inclusion substance may be added and milled.

In the milling step, one or more components selected from a thickening agent, surfactant and a dispersion media may be added, and one or more components selected from a preservatives and an inclusion substance may be further added, followed by the milling.

Examples of the milling method include, but are not particularly limited to, dry milling and wet milling. Wet milling is preferred.

The wet milling more preferably comprises adding a dispersion media to the vascular endothelial growth factor (VEGF) receptor inhibitor or the epidermal growth factor (EGF) receptor inhibitor, followed by the milling.

Test Example 7 Anti-Angiogenic Effect of Nanoparticle Composition of Present Invention on Laser-Induced Choroidal Neovascularization Model of Rat

This test aims at evaluating whether or not the nanoparticle composition of the present invention exhibits an anti-angiogenic effect on a laser-induced choroidal neovascularization model of a rat, which is a typical wet age-related macular degeneration model.

The mydriasis of the eyeballs of each male Brown Norway rat (n=12 or 13 for each group) was caused with mydriatic eye drops for examination. A ketamine hydrochloride/xylazine hydrochloride (7:1, v/v) mixed solution was intramuscularly administered (1 mL/kg) to the femur for general anesthesia. Then, the right eyeground was observed using a slit lamp, and 8 sites in the retina were irradiated with laser (wavelength: 532 nm, spot size: 80 μm, irradiation time: 0.05 sec, output: 120 mW) using a multicolor laser photocoagulator to prepare laser-induced choroidal neovascularization model animals.

A vehicle of Example 1 or the nanoparticle composition of the present invention obtained in each of Examples 1 and 2 was administered twice a day by ocular instillation (5 μL/eye, 6 hr:18 hr interval) to each model animal from immediately after the laser irradiation to 14 days after the laser irradiation. Aflibercept (EYLEA(Registered Trademark) solution for intravitreal injection, Bayer Corp.) was intravitreally injected (5 μL/eye, once) thereto immediately after the laser irradiation.

Fourteen days after the laser irradiation, a 4% (v/v) FITC-dextran solution was administered (1 mL/animal) to the tail vein under general anesthesia. The animal was euthanized by excessive anesthesia through isoflurane (Mylan N.V.) inhalation, and the eyeballs were excised. The excised eyeballs were fixed for 24 hours in a 0.1 mol/L phosphate buffer solution containing 4% paraformaldehyde (PFA).

In order to prepare a choroid flat mount preparation, a hole was made in the corneal limbus of the eyeballs thus fixed using an injection needle under a stereoscopic microscope (EZ-4, Leica Microsystems GmbH), and the whole cornea, the iris and the crystalline lens were resected starting at the hole to create an optic cup state. Retina tissues other than retinal pigment epithelial cells were detached, and the optic cup was divided. Fluoromount (Diagnostic BioSystems (DBS)) was added dropwise thereto. A preparation was prepared by enclosure with a cover glass and dried at 4° C. for 24 hours in the dark.

A choroidal neovascular site was photographed using a confocal microscope (Nikon ECLIPSE TE 2000-U). For choroidal neovascular evaluation, an area (unit: pixel) that contained a newly formed blood vessel and was at the inner side relative to the highest raised portion was calculated using ImageJ (National Institutes of Health). Then, an average neovascular area of 3 or more sites, except for obscure laser irradiation sites, among data on the 8 sites per eye was used as an individual value to calculate an average area of each group. For statistical processing, the Bartlett test was conducted on the aflibercept (EYLEA(Registered Trademark) solution for intravitreal injection, Bayer Corp.) administration group, the Example 1 administration group and the Example 2 administration group vs. the vehicle group. In the case of equal variance, the Dunnet test was conducted. The tests employed statistical analysis software (Stat Light, Yukms Co. Ltd.), and the significance level was set to 5% (two-tailed test) in all the tests. The results are shown in FIG. 2 and Table 45.

When the nanoparticle compositions of the present invention obtained in Examples 1 and 2 were administered by ocular instillation to the laser-induced choroidal neovascularization models of rats, an anti-angiogenic effect equivalent to or higher than that of aflibercept (EYLEA, intravitreal injection) was confirmed.

Test Example 8 Pharmacological Effects of Nanoparticle Composition of Present Invention and Solution of Comparative Example on Laser-Induced Choroidal Neovascularization Model of Cynomolgus Monkey

This test aims at evaluating whether or not the nanoparticle composition of the present invention exhibits a pharmacological effect on a laser-induced choroidal neovascularization model of a cynomolgus monkey, which is a typical wet age-related macular degeneration model.

Twenty-one days before the start of drug administration, both the eyes of each animal (all cases) were irradiated with laser to prepare animal models. Drops of a mydriatic agent were placed in the animal eyes to be irradiated. After confirmation of mydriasis, a mixed solution of ketamine hydrochloride (50 mg/mL) and an aqueous xylazine solution (20 mg/mL) [7:1 (v/v)] was intramuscularly administered (0.2 mL/kg or 10 mg/kg) to each animal. An appropriate amount of a special aid for contact lens placement to the cornea (Scopisol Solution for Eye) was added dropwise to an eyepiece of a retinal laser lens. The retinal laser lens was pressure-bonded to the eyes to be irradiated, and a yellow spot was confirmed. After the confirmation of a yellow spot, 8 sites around the yellow spot excluding the central pit were irradiated with green laser (wavelength: 532 nm, irradiation spot size: 80 μm, irradiation time: 0.1 sec, output: 1000 mW) using a multicolor laser photocoagulator (MC-500, Nidek Co., Ltd.).

According to the test configuration shown in Table 46, a vehicle, the nanoparticle composition of the present invention prepared according to Example 1, and the solution composition obtained in Comparative Example 2 were administered four times a day by ocular instillation for 35 days to the animal. Aflibercept (EYLEA(Registered Trademark) solution for intravitreal injection, Bayer Corp.) was intravitreally injected (once) to the animal.

Ophthalmoscopic examination was carried out during the acclimatization period (day −1) and during the administration period (administration days 7, 14, 21, 28 and 34). Macroscopic examination and light reflex examination were carried out using a portable slit lamp (SL-15, Kowa Co., Ltd.). Drops of a mydriatic agent were placed in the animal eyes. After confirmation of mydriasis, ketamine hydrochloride (50 mg/mL) was intramuscularly administered (0.2 mL/kg or 10 mg/kg) to each animal. The anterior segment of the eye and the ocular media were examined using a portable slit lamp, while the eyegrounds were examined using a head-type binocular indirect ophthalmoscope (IO-aSmall Pupil, Neitz Instruments Co., Ltd.). The eyegrounds were photographed using a fundus camera (VX-10a, Kowa Co., Ltd.) in all cases.

Fluorescein fundus angiography was carried out during the acclimatization period (day −1) and during the administration period (administration days 7, 14, 21, 28 and 34). For examination, a contrast medium (Fluorescite Intravenous Injection 500 mg, Alcon Japan Ltd.) was administered (0.1 mL/kg or 0.1 mL/s) from the cephalic vein of the forearm under mydriasis and anesthesia of the macroscopic examination and the ophthalmoscopic examination. Approximately 1, 3, and 5 minutes after the contrast medium administration, photographs were taken using a fundus camera. Choroidal neovascular grading was carried out on an irradiation spot basis. The fluorescein fundus angiographic images were observed and graded on an irradiation spot basis according to the criteria of Table 47.

a) Fluorescein fundus image taken approximately 1 minute after the contrast medium administration

b) Fluorescein fundus image taken approximately 3 minutes after the contrast medium administration

c) Fluorescein fundus image taken approximately 5 minutes after the contrast medium administration

The incidences of grades 1 to 4 of each eye at each point in time of examination were each calculated according to the following expression:

Incidence of grade (%)=The number of irradiation spots/8×100

The results about the incidence of grade 4 are shown in Table 48 and FIG. 3.

This test aims at evaluating whether or not the nanoparticle composition of the present invention exhibits a pharmacological effect on an oxygen-induced retinopathy model of a mouse, which is a typical diabetic retinopathy model.

Each immature (1-week-old) 129SVE mouse (n=10 to 12 for each group) was subjected to high-oxygen loading treatment (under 75% oxygen, 5 days). Then, a vehicle or the nanoparticle composition of the present invention prepared in accordance with Example 1 was administered twice a day (once between 8 a.m. and 9 a.m. and once between 4 p.m. and 5 p.m.) by ocular instillation (2 μL/eye) to the right eye for 5 days under normal oxygen. After the completion of the administration period, ketamine/xylazine was intraperitoneally administered thereto for anesthesia, and the animal was euthanized by the intraperitoneal administration of Euthasol. The eyeballs were excised and fixed by treatment with 4% paraformaldehyde at room temperature for 1 hour. Retina tissues were isolated from the fixed eyeballs and stained with a calcium chloride buffer solution containing Isolectin-B4. The eyeballs were washed, and a flat mount preparation was then prepared. A neovascular area (the ratio of a neovascular area to the total tissue area of the retina) in the retina was evaluated under a microscope.

For statistical processing, significant difference was tested by the unpaired t-test on the administration group of the pharmaceutical composition of the present invention prepared according to Example 1 vs. the vehicle group. The tests employed Graphpad Prism as statistical analysis software, and the significance level was set to 5% in all the tests.
